Abstract

Spectrally and temporally heterodyned four-wave mixing (FWM) signals in silver thiogallate are reported over a wavelength range of 3 10 μ m . We (1) expose the usefulness of the strong nonresonant FWM in optimizing an apparatus for heterodyned 2D infrared experiments and (2) use heterodyning to measure the 2D phase of a frequency-resolved optical gating (FROG) signal. We report the phase of the 2D FROG signal, as opposed to the 1D phase of the excitation pulses routinely determined from conventional FROG analysis. The 2D FROG phase complements the 2D FROG magnitude in providing intuitive visual analysis of the spectral and temporal phases of femtosecond pulses.
